What Are the Reasons for Increasingly Louder Car Engine Noise?

[SanXavier]

Car engine noise becomes increasingly louder due to the following reasons: 1. Excessive carbon buildup in the engine; 2. Inappropriate engine oil usage or dirty engine oil; 3. Loose screws on the engine underguard; 4. Aging engine mount pads; 5. Loose plastic components in the engine compartment. An engine is a machine capable of converting other forms of energy into mechanical energy, originating in the UK. It can refer to both the power generation device and the entire machine including the power unit (such as gasoline engines, aircraft engines). Its types include internal combustion engines (e.g., gasoline engines), external combustion engines (e.g., Stirling engines, steam engines), and electric motors, among others.
